Abstract: The main factors that affect the productivity of horizontal wells in ND volcanic reservoir are uncertain, and the conventional productivity calculation formulas for horizontal wells predict high productivity with large error. Based on the geological, engineering and dynamic data of volume fracturing of horizontal wells in ND volcanic reservoir, the influencing factors of initial productivity after volume fracturing were analyzed by grey correlation analysis. On this basis, normalized productivity of single well was accumulated by grey theory, and then multiple linear regression method was used to predict the initial productivity after fracturing. The results show that the first four factors influencing the initial productivity after volume fracturing are the amount of sand in the well,the drilling rate of the oil layer,the amount of the well fluid and the number of fracturing stage. After normalization,the initial productivity predicted by multiple linear regression after volume fracturing is more accurate than that predicted by traditional direct multiple linear regression method. This study provides an effective method for predicting productivity of horizontal wells in similar reservoirs.
